Abstract

La présente invention concerne un système d'amplificateur à correction aval à désynchronisation des retards, utilisant un système et un procédé de commande mettant en oeuvre des planchers et des pénalisations. Le système et le procédé de commande de l'invention permettent de décaler, de façon répétable et contrôlée, le réglage du correcteur de phase de la deuxième boucle. Le recours aux planchers et aux pénalisations pour décaler le réglage du correcteur de phase à l'état stabilisé modifie la logique conventionnelle de suppression du pilote. Avec la logique conventionnelle, la suppression du pilote comporte un minimum distinct qui correspond au réglage de la correction désirée. Avec la logique de l'invention, la suppression mesurée du pilote set bloquée à une limite inférieure ou un plancher donnant un ensemble de résultats de commande minimaux d'égales valeurs. Le choix du plancher se fait de façon à amener le décalage désiré de la phase destinée au correcteur de phase, au bord du plancher minimum. Pour garantir que c'est bien le bon décalage du correcteur de phase qui est choisi dans l'ensemble de résultats de commande minimaux d'égales valeurs, on a ajouté une pénalisation se basant sur le sens de la commande. L'ajout aussi bien du plancher que de la pénalisation fait que le décalage à l'état stabilisé du correcteur de phase sera systématiquement d'une valeur correspondant au bord du plancher minimum.
